Optical Bonding Services

The optical joint (bonding) technology introduced

Ordinary strengthening monitor is in front of the LCD panel with a layer of shielding or protect the glass. There is an air space between the glass and the liquid crystal box, thus from outside to inside to form three reflector: air - glass, glass - air, air - polaroid. If there is no special treatment, every reflection in the face of external light reflectivity roughly 4.5%, three reflective surface reflection of the external light is 13.5%, to 1350 lumens. If the brightness of the screen backlight is 1000 lumens, we can see this is the display picture has run out. Common have the brightness of the light is lower than the reflection of the reinforcement display brightness. The reflected light make white brighter, covered in black and other colors. So the reflected light greatly reduces the contrast, the LCD screen in bright light readability is poor.

Optical binding reinforcement displays

In order to increase the readability of the LCD screen in bright light, must increase the external contrast of the LCD panel. External contrast and the interior of the LCD contrast are two different concepts. Internal contrast ratio does not consider the surrounding light and reflection, is in the LCD screen surface measuring the ratio of the brightness of white and black; And external contrast observation from a distance, the LCD panel brightness difference. The definition is as follows:

External contrast (display through the brightness + the brightness of the reflected light)/reflection brightness

From the visible and increase the display backlight brightness and reduce the brightness of the reflected light can increase external contrast values. If you don't reduce the brightness of the reflected light but only increasing the brightness of the backlight would increase the power consumption of the LCD panel, fever will reduce the reliability of the monitor. Therefore, the fundamental method is to reduce the brightness of the reflected light.

Man-machine interface minimum external contrast should be greater than 3. Optical adhesive binding after minus reflection shield or protection glass, external contrast is increased, the increase of the external contrast the picture clearly visible.Optical binding not only greatly improve the readability of reinforcement displays under strong light, but also increase the reliability of the reinforcement displays in harsh environment. Its advantages are as follows:
